Setting up Conversion API (Capi)

Deadlines

I am very satisfied with the collaboration. The freelancer successfully set up the Meta Pixel and Conversions API for the online store on WordPress, fixed event duplication, and configured the correct transmission of all necessary parameters (email, phone, fbp, fbc, value, currency).

It is also important that the Purchase event is now transmitted only after payment confirmation from Monobank, so the analytics and ad optimization work correctly.

The work was completed quickly, the freelancer was always in touch, explained everything in detail, and promptly fixed all technical issues. I recommend for collaboration.
